Dual Graphics cards but only 1 gpu's Graphic memory

Hello Forum, im CrazyKilla

Yesterday my 2nd GeForce GTS 450 arrived, i put it in the pc, set all the wires up, i even put SLI on my 2 graphics cards, and now i got 2 graphics cards, but the problem is, (GTS 450 has 1gb graphics memory) i got 2 GTS 450s but i only have 1gb of graphics memory, how does this work? i should have 2gb graphics memory!

I know that the graphics card is working as the FPS in my games has boosted a lot and in the "Display Adapters" section in "Device Manager" it shows i have 2 GTS 450s,

Help please, i have latest drivers for both cards, do i need to install any special things or have i done something wrong here?

Similar to CPU-Z.

It would show each GPU seperately.

Click the drop curtain I have circled in yellow in the picture below and both cards should be listed.

Click each one for details on that card. I don't think it will give you a total GB of memory.
It is not like RAM where you get a total of all slots added together.

I think you will find Windows 7 only recognizes the primary GPU in the WEI rating system and other specifications.
Win7 just does not report the SLI for specification purposes.

well it shows both GTS 450s, the new one by EVGA and old one by PNY, both gpus 1024MB, but why can't i merge these graphics cards and make PC think its like just 1 big GPU, and then shit should work faster and i should have more graphics memory, why should i be limited to 1gb?

You are not limited.

Windows just does not report SLI in the specifications.

The second card is used in the games or the FPS -frame rate- would not increase over a single card.

Each video card uses its own memory it is not added together as RAM on a motherboard.

quick question, can i have both cards inserted into the motherboard, then 1 card connected with the wire and the other just connected to board and to the other card with SLI (1 card with wire 1 without, both connected with SLI)?

And does that mean im stuck with 1gb until i get a GPU with higher graphics memory?

SLI requires that the same data be copied into the video RAM of both cards. In effect, your VRAM will be that of a single card. It's done to increase graphics processing performance, not available memory.

If you need more than 1GB, you'll need cards with more VRAM (each).

damn, i wish i could sell both cards and buy something expensive, is it possible to do so? i mean this new card is taken out the box and used for a while, and the old one is old but maybe i could sell it somewhere?

Sure, you can sell both cards and buy a better one, it's done all the time.
